Class
    Foam::functionObjects::icoUncoupledKinematicCloud
 
Group
    grpLagrangianFunctionObjects
 
Description
    This functionObject tracks a uncoupled kinematic particle cloud in the
    specified velocity field of an incompressible flow (laminar, RANS or LES).
 
    It may be used in conjunction with any transient single-phase incompressible
    flow solver such as pisoFoam or pimpleFoam and tracks the particles or
    parcels without affecting the flow-field.
 
    The kinematicCloud requires the density of the fluid which is looked-up
    from constant/transportProperties dictionary and the acceleration due to
    gravity which is read from the constant/g file if present or defaults to
    zero.
 
    The kinematicCloud properties are read from the
    constant/kinematicCloudProperties dictionary in the usual manner.
 
Usage
    Minimal example by using \c system/controlDict.functions:
    \verbatim
    tracksFO
    {
        // Mandatory entries
        type              icoUncoupledKinematicCloud;
        libs              (lagrangianFunctionObjects);
 
        // Optional entries
        U                 <word>;
        kinematicCloud    <word>;
 
        // Inherited entries
        ...
    }
    \endverbatim
 
    where the entries mean:
    \table
      Property  | Description                        | Type | Reqd | Deflt
      type      | Type name: icoUncoupledKinematicCloud | word | yes  | -
      libs      | Library name: lagrangianFunctionObjects | word | yes  | -
      U         | Name of the velocity field         | word | no | U
      kinematicCloud | Name of the cloud      | word | no | kinematicCloud
    \endtable
 
    The inherited entries are elaborated in:
